以鹤庆盆地168m深度岩芯花粉记录为基础，通过1.0Ma以来古植被演化和气候变化研究，探讨植被和气候对构造隆升的响应。明显的气候转变发生在0.73MaBP和0.42-0.365MaBP。林线对16.5kaBP运动的响应不是很明显，这可能与山体抬升的临界高度导致稳定垂直谱的形式有关。 13.2kaBP时，构造运动产生的差异抬升导致鹤庆古湖被夺取。
The vegetation and climate response to tectonic uplifts is discussed through the study in palaeovegetation evolution and climate changes since 1.0Ma, based on pollen records from the core with 168m depth in Heqing basin. Obvious transitions of climate occured at 0.73MaBP and 0.42-0.365MaBP. The tree line response to the 16.5kaBP movement was not very clear, which might be related to a critical height of mountain uplift resulting in the form of stable vertical spectrum. At 13.2kaBP, the differential lift due to tectonic movement led to the capture of Heqing palaeolake.
